slice2ts npm version Build Status

Compiles Slice files to TypeScript.

Installation

$ npm install -D slice2ts

Usage

Usage: slice2ts [options] <file ...>

Options:

  -V, --version         output the version number
  --root-dir <dir>      Root dirs.
                        Output files will have the same structure as source files relative to root dirs.
                        Ice includes are also resolved in these dirs.
  -e, --exclude <file>  File paths or globs to exclude.
  -o, --out-dir <dir>   Directory where to put generated files.
  --no-js               If true, only the typings are generated.
  --ice-imports         If true, Ice modules are imported from particular files instead of "ice".
  -i, --ignore <type>   Don't generate typings for these types.
  --index               If true, generates index file for each top-level slice module.
  --no-nullable-values  If true, don't generate `| null` for fields and parameters whose type is Value.
  -h, --help            output usage information

Metadata Directives

  • ts:type:<type>

    Overrides generated type for fields, operation parameters or operation return values:

    class AbstractBase {};
    class A extends AbstractBase {};
    class B extends AbstractBase {};
    
    struct S {
      ["ts:type:A|B"]
      AbstractBase field;
    };
    
    class C {
      ["ts:type:A|B"]
      AbstractBase field1;
    
      ["ts:type:A|B"]
      optional(1) AbstractBase field2;
    };
    
    interface I {
      ["ts:type:A|B"] AbstractBase operation(
        ["ts:type:A|B"] AbstractBase arg1,
        ["ts:type:A|B"] optional(1) AbstractBase arg2
      );
    };

    Outputs:

    class AbstractBase extends Ice.Value {}
    class A extends AbstractBase {}
    class B extends AbstractBase {}
    
    class S implements Ice.Struct {
      constructor(field?: A | B);
    
      field: A | B;
    
      clone(): this;
      equals(other: this): boolean;
      hashCode(): number;
    }
    
    class C extends Ice.Value {
      constructor(field1?: A | B, field2?: A | B | undefined);
    
      field1: A | B;
      field2?: A | B;
    }
    
    abstract class I extends Ice.Object {
      abstract operation(
        arg1: A | B,
        arg2: A | B | undefined,
        current: Ice.Current,
      ): Ice.OperationResult<A | B>;
    }
    
    class IPrx extends Ice.ObjectPrx {
      operation(
        arg1: A | B,
        arg2?: A | B,
        ctx?: Ice.Context,
      ): Ice.AsyncResult<A | B>;
    }
  • ts:generic:<type parameters>

    Adds generic parameters for types generated from sequences, dictionaries, classes and interfaces:

    ["ts:generic:T extends Ice.Value"]
    sequence<["ts:type:T"] Object> GenericSeq;
    
    ["ts:generic:T extends Ice.Value"]
    dictionary<string, ["ts:type:T"] Object> GenericDict;
    
    ["ts:generic:T extends Ice.Value"]
    class GenericClass {
      ["ts:type:T"]
      Object field;
    };
    
    ["ts:generic:T extends Ice.Value"]
    interface GenericInterface {
      ["ts:type:GenericClass<T>"] GenericClass operation(
        ["ts:type:GenericSeq<T>"] GenericSeq arg
      );
    };

    Outputs:

    type GenericSeq<T extends Ice.Value> = Array<T>;
    
    type GenericDict<T extends Ice.Value> = Map<string, T>;
    const GenericDict: {
      new <T extends Ice.Value>(entries?: ReadonlyArray<[string, T]>): Map<
        string,
        T
      >;
    };
    
    class GenericClass<T extends Ice.Value> extends Ice.Value {
      constructor(field?: T);
    
      field: T;
    }
    
    abstract class GenericInterface<T extends Ice.Value> extends Ice.Object {
      abstract operation(
        arg: GenericSeq<T>,
        current: Ice.Current,
      ): Ice.OperationResult<GenericClass<T>>;
    }
    
    class GenericInterfacePrx<T extends Ice.Value> extends Ice.ObjectPrx {
      operation(
        arg: GenericSeq<T>,
        ctx?: Ice.Context,
      ): Ice.AsyncResult<GenericClass<T>>;
    }
